Understanding Tropical Cyclone Risk: from Mountain Drivers to Economic Impacts
Over the past decade, multiple methods to model tropical cyclones have neared maturity. State-of-the-art global climate models (GCMs) now reach resolutions of 25-50 km in the atmosphere, permitting the simulation of realistic tropical cyclone intensities and tracks. Additionally, statistical-dynamical tropical cyclone models now allow the computationally cheap simulation of many physically plausible tropical cyclones. I will describe recent and ongoing research using these methods to both better understand the drivers of tropical cyclones in different ocean basins, and determine the risks to human society from these extreme events. I will first discuss work using the GCM GFDL CM2.5-FLOR to understand the influence of two different orographic features on the regional climatology of tropical cyclones: 1) the Tibetan Plateau (and related mountains) on the western north Pacific, and 2) the topography of Central America on the eastern tropical Pacific. I will demonstrate the importance of rigorously considering atmosphere-ocean coupling in such analyses, and argue that a relatively small orographic feature can have an outsize climatic influence contingent on its placement relative to the larger-scale circulation. Next I will introduce ongoing work in collaboration with World Bank economists to improve disaster risk assessment using Columbia’s statistical-dynamical tropical cyclone model. I will highlight both challenges and significant opportunities in such hazard to impact modeling.

As Zhaohua mentioned, please join us starting from 3 PM to “meet the speaker” and have informal discussion.
GRADUATE STUDENTS: There will be a student Q&A with the speaker to be held immediately following the seminar - so students, please join and stay after the seminar for your chance to talk with Dr. Baldwin about work/life/career topics. Graduate student Jake Carstens will moderate the student Q&A.
The seminar will be recorded if you are unable to attend live, but we hope to see many of you there! If anyone would like to meet with Dr. Baldwin earlier in the day or any time after the seminar, you are welcome to get in touch with her (jbaldwin at ldeo.columbia.edu<mailto:jbaldwin at ldeo.columbia.edu>).
Allison, Zhaohua, & Philip
